LED Troubleshooting - Using a Voltage Meter A Voltage Multimeter is the most important tool to have when troubleshooting an LED installation issue. They range in price from tens to hundreds of dollars.. The most versatile tool is a multimeter, but depending on the complexity of the PCBs and the problem, an LCR meter, oscilloscope, power supply and logic analyzer may also be needed to dig deep into the operational behavior of the circuit..
Мы участвуем в выставке ЭкспоЭлектроника в Крокус Экспо в Москве, Россия 17 - 19 апреля 2018. It's probably not new to you, but sometimes we want to analyze a powered circuit with a multimeter. I love to do that, but I'm a little worried that I might burn some components or the whole circuit.

A multimeter must be inserted in series in a circuit in order to measure current. See the diagram below. See the diagram below. Turn the dial on the meter to the highest current range (or the 10A range if the probe is in the 10A socket).. A test of circuit-board components, such as capacitors, resistors, transistors and integrated circuits, can be done to some extent without removing the components from the circuit board. More comprehensive testing can be performed on these components when the component is removed. Most technicians, though, when attempting to diagnose if a circuit board component is faulty, use a volt meter ….

Check the inputs to the circuit: Likewise, if the signal inputs are not reaching the board then it will not be able to perform. Again any switches, and connectors along with any broken wires should be checked. Often a multimeter can be used to check the continuity of the wires, but first ensure there is no power applied to the circuit.. How to Test Resistors. Resistors regulate the amount of current flowing in an electronic circuit. Resistors present a resistance, or impedance, to the electrical circuit and reduce the amount of current that is allowed to flow. Resistors.... This guide helps you replace the Fluke 77 Series III Multimeter's PCA. The PCA is the main circuit board of the Multimeter and is therefore its most important part..
